VThis invention relates to vertically sliding .windows for rail and roadvehicles, vmore'par-` ticularlyV ,for automobile doors.V It comprises"also a window operating mechanism and a 5 locking device for'liXingitvin any position.

object of the invention is to` provide struction of heretofore. i 1eAnother object. of the invention is to improve the sliding bracketssupporting the window. Y i

A further object ofthe invention is toprovide means ffor raising andlowering the 1 5 window. Y Y

A still further object is to provide alock ing device Vfor fixing thewindow in anyposition., A r Theinvention also consists incertain otherfeatures of construction,- to be` hereinafter fully described,illustrated lin the drawings and specificallypointed out in the appendedclaims. A j

In describing the inventionv in" detail, reference will he had to theaccompanying drawings wherein like characters denote like "partsthroughout vthe several views, inwhich:

Referring particularly to Figs. 1 tch-.which illustrateajirst embodimentof the Vinvention,` A denotes theV glass pane. proper, they) o y lateraledges ofwhich are assumed'to bever-- a window sash Cof greatstilfness`the conf i which is moreV economical than tical. kAccording lto theinvention, `,the sash ofthe window is, asshown in Fig. 3, `constiand acage S1,^for the vertical, flat, ironC,

yxed to the window` sash. The tubular elementsmay be made bysuitably-'bending ordinary seamless tubes'. 'This flat iron is slightlyk'60 deflected outside Vits lodgement in the Vsash vand its lowerend isset between Ythe forward *i iangesIof aV vertical I iron, F, pla ced atthe underside of the window andadapted to constituteonelofthetwo slidingbrackets of said l65 f window. In they other pair.. of the I iron 'aflanges is setthe vertical branch, G`, of an anf gle iron the horizontalbranch of lwhich G1, is fixed to the underside of the horizontal vlowerpart of thewindowsash in the tubular recessy thereof;A These threeirons,C, F and G-G1 Y are tightly held togetherby any means, for

instance `by, means of-screws, thus constituting a bracket vforsupporting the window and guiding it'in the door slot. yOwing to theparticular connection ofthe-vertical flat iron C with the angle ironGrGr1k through the medium ofthe. I iron, F, the whole of the con-`struction is endowed with'V a greatstiffness.

'The devicefor .guidingthe window in the S5 The up'perend of'the'U orVchannel iron D, is sliton` acertainlength (Figsl, 2,' 4') this partofthefchannel iron-isflodged' in a 'casing K, set in the door pane,`and inwhich works a set screw L,provid ed with allock-nut the the window sash(Fig. 3) which rack meshes in a known manner with al spul' pinion, keyedon a shaftl O, the ends of Wllichrotate in the fixed part of the fdoor,and o'n'wli'ich` is fast a high pitched glob'oid worm P meshing with aworm wheel Q.
